Abstract: A method for calibrating alignment of a radar sensor in an installation environment. The method includes: measuring, with a velocity measuring device that is stationary relative to a global reference system, a velocity component of a reference object in a direction parallel to a reference axis of the installation environment, measuring, with the radar sensor, an angular deviation between the position of the reference object and an optical axis of the radar sensor, calculating an anticipated radial velocity of the reference object relative to the radar sensor, assuming that the optical axis of the radar sensor is parallel to the reference axis, measuring the radial velocity of the reference object with the radar sensor, and calculating a misalignment angle between the optical axis of the radar sensor and the reference axis, based on the difference between the measured and the anticipated radial velocity.

Abstract: A method for recognizing misalignments of a stationary sensor. A first occupancy map is generated based on first sensor data, which the sensor generates at a first point in time. Based on second sensor data, which the sensor generates at a second point in time, a second occupancy map is generated. A cross-correlation of the first occupancy map and of the second occupancy map is calculated. A misalignment of the sensor is recognized based on the calculated cross-correlation.
